Polaris, the North Star, is a yellow supergiant roughly 447 light-years away that lies nearly in line with Earth's rotational axis, so it appears almost motionless in the sky and has long served navigators; it is also a classical Cepheid variable, a type of pulsating star important for measuring cosmic distances.
